	Check
 Danger!	Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by swallowing coolant.	Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses.	AS20.00-Z-0001-01A
1	Unscrew cap (1) on filler neck (2) of cooling system
2	Check coolant level	 Check coolant level and adjust to correct level only if coolant temperature is below 50 °C. The cooling system is correctly filled if coolant is visible in the filler neck (2). Before adjusting coolant to correct level, inspect anticorrosion/antifreeze protection.
3	Inspect anticorrosion/antifreeze protection	 To do this, drain coolant from radiator coolant drain plug if required.
		Antifreeze tester
		Very little anticorrosion/antifreeze protection: 
		Correcting anticorrosion/antifreeze concentration - subject to separate repair order.	AP20.00-W-2010-01G
